### Key updates
- It turned out that FreeRTOS added no value, so it was removed
- DFU can be achieved by jumping directly into the ROM bootloader, so there is no need for hardware to manipulate the BOOT0 pin
- The TX_DISABLE signal is now supported. It is active low in board 9.x and active high in board 10.x and higher
- Board 9.3 adds 3 "status" (LED driving) signals for GPS, RX and TX
- Board 10.x needed a GPIO swap to make routing viable and inverted the logic of the TX_DISABLE signal, but it's all abstracted in the BSP
- The new 'cli' command was introduced to reboot the board into 'quiet' mode, making it a lot easier to program and verify the station data
- Station metadata is now stored in MCU flash, so it is handled in the Configuration class instead of the BSP. The EEPROM is obsolete.
- Station metadata is now stored in EEPROM again.
### Building and flashing

The project supports the following STM32 MCUs: L412, L422, L431 and L432.
The openocd-flash-*** scripts in this folder can be run against an STLink programmer to flash the corresponding binary directly to the MCU without any kind of Debug session in Eclipse.
There are multiple build configurations. Some of these configurations can be installed directly at address 0x08000000, without any bootloader.
Configurations with "bootloader" in the name are linked for use with the new MAIANA bootloader only and will not function if installed at the top of flash.
